DC 38 tselluloosi- ja paberitööstuse reovee sekundaarseks töötlemiseks
Select suitable MBBR media, such as DC 38. High-quality media should possess characteristics such as a large specific surface area, light weight and corrosion resistance, to ensure uniform air-water mixing; the air flow rate and aeration method should be adjusted appropriately.
Kirjeldus
How can biofilm blockages and agglomeration of MBBR media be addressed in a biochemical reactor?
Select suitable MBBR media, such as DC 38. High-quality media should possess characteristics such as a large specific surface area, light weight and corrosion resistance, to ensure uniform air-water mixing; the air flow rate and aeration method should be adjusted appropriately.
DC 38 tselluloosi- ja paberitööstuse reovee sekundaarseks töötlemiseks
38 auguga vertikaalse triibuga eenduv MBBR-materjal on suure tõhususega biokile kandja, mis on loodud tasakaalustatud jõudluse tagamiseks munitsipaal- ja tööstusreovee puhastamisel. Selle optimeeritud geomeetria hõlmab 38 strateegiliselt jaotatud läbivat auku koos aksiaalselt joondatud vertikaalsete reljeefsete triipudega, luues turbulentseid voolumustreid, mis parandavad massiülekannet ja kaitsevad biomassi nihkejõudude eest. UV-stabiliseeritud suure tihedusega polüetüleenist (HDPE) valmistatud materjal pakub kaitstud pinda ≥800 m²/m³ ja erakordset tühimike mahtu (>95%) ummistumise vältimiseks. Triibulised eenduv osad loovad mikroelupaiku biokile tugevaks arenguks, mistõttu on see ideaalne BOD eemaldamise, nitrifikatsiooni ja denitrifikatsiooni protsesside jaoks MBBR-is, IFAS-is ja hübriidreaktorsüsteemides.
How can the problem of an effective biofilm failing to form for a prolonged period after the addition of packing material, resulting in poor treatment performance, be resolved?
Use hydrophilic-modified DC 38 HDPE media to accelerate biofilm formation; maintain the pH within 7.0–8.5; control dissolved oxygen (DO) at 3–4 mg/L during the initial biofilm formation stage; alternate 15 minutes of aeration with 5 minutes of rest to prevent high-intensity aeration from dislodging the early biofilm; and start with a COD load of ≤0.5 kg/(m³·d), increasing it by 20 per cent every three days.

1. Kõrge eripindala
With a specific surface area of more than 800 m²/m³, DC 38 provides abundant attachment space for microorganisms, helping increase the effective biomass in the biological reactor.
2. 38-Hole Biofilm Protection Structure
The 38-hole cylindrical structure provides multiple internal channels and external surfaces for biofilm growth. These protected channels help microorganisms attach more stably and reduce biomass loss caused by aeration or hydraulic scouring.
3. Tõhus massiülekande jõudlus
The porous, open structure of DC 38 facilitates thorough contact between wastewater, dissolved oxygen, and the biofilm, allowing oxygen and pollutants to penetrate the biofilm more effectively, thereby improving the efficiency of organic matter degradation and ammonia nitrogen removal.
4. Suurepärane fluidiseerimisefekt
DC 38 has a density of 0.94–0.97 g/cm³, which is close to that of water. When aerated or propelled by water flow, the packing material remains well suspended and fluidized in the reaction tank, making it unlikely to settle at the bottom of the tank, which helps improve packing utilization and system operational stability.
5. Valmistatud 100% valgest neitsi HDPE-st
The DC 38 is made from 100% virgin white HDPE material and offers excellent chemical stability, corrosion resistance, and weather resistance, making it suitable for long-term use in municipal sewage and industrial wastewater treatment systems.
6. Pikk tööiga
The DC 38 has a service life of up to 15 years, which reduces the frequency of media replacement and lowers the long-term operating and maintenance costs of wastewater treatment systems.
7. Paindlik täitesuhe
The DC 38 has a packing density range of 15%–70% and can be flexibly designed to accommodate different water qualities, organic loads, tank volumes, and effluent requirements, making it suitable for wastewater treatment projects of various scales.
8. Sobib COD, BOD ja ammoniaagi-lämmastiku eemaldamiseks
DC 38 provides a stable attachment environment for heterotrophic bacteria and nitrifying bacteria. It is suitable for COD and BOD degradation as well as ammonia nitrogen removal in wastewater treatment, helping to improve the system’s biochemical treatment efficiency.
9. Suitable for High-Load Wastewater Treatment
Because DC 38 has a high specific surface area and a 38-pore structure, it can increase microbial concentration within a limited tank volume, making it suitable for wastewater treatment projects with high loads and stable effluent quality requirements.
10. Sobib MBBR ja IFAS uuendamiseks
DC 38 can be added to existing biological treatment tanks to increase the microbial concentration and treatment capacity within the system. It is suitable for new MBBR systems, upgrading and retrofitting of existing wastewater treatment plants, and IFAS process upgrade projects.

How to address the issue of media breaking down after several years of operation, with fragments entering subsequent treatment units
Select high-quality HDPE media manufactured by Decycle, with a compressive strength of ≥25 N per particle and an outdoor service life of ≥15 years. Carry out regular inspections to check for media wear and tear, replacing 10–20 per cent of the old media annually whilst mixing new and old media together. Any damaged media should be retrieved and removed promptly upon discovery.
